What happens when opposite terminals of car battery are connected?

Connecting a battery backwards takes some effort as the terminal are different.
If u do, the computer systems may not be too happy resulting in a LARGE repair bill.
If u try to start it more trouble is at hand since the starter won't engage and if it does it will run backwards.
The generator diode will also not be happy and may turn very black.

Why is a 1997 Toyota Corolla battery clicking?
More than likely you have corrosion at the terminals. Clean the battery terminals and then recharge the battery and see what happens.
What happens when you hook up battery terminals to a wet battery?
It's gonna have a short.
What will happen if one battery terminal is connected to a terminal?
Nothing. An auto battery system is 12V DC. If both terminals aren't in the loop (positive through the current path and back to negative) nothing happens.
Nothing happens when you turn the key on your 91 cutlass supreme?
dead battery or try taking the battery terminals off and cleaning the terminals and battery cables with a wire brush and rehook.
What happens to the current in a circuit if a volt battery is removed and is replaced by a 3 volt battery?
The battery cannot be removed quickly! Inductance of the wiring stores energy and keeps the current flowing and decaying smoothly. There will be an opposite polarity, higher voltage pulse on the battery terminals, limited by the circuit capacitance only.
What happens if two lots of 12dc volts are applied?
It depends how they are connected. If the terminals of two 12 volt batteries batteries are connected to the same circuit (in parallel) then there is no change in the flow of current- it will just last for twice as long a time. But if two opposing terminals of the batteries are connected to each other first and the free terminals then connected to the circuit (in series) then there would be a total voltage of 24 volts and twice as much current would flow. The two batteries would last for the same length of time as one battery on its own.
What happens to the current in a circuit if a 1.5-volt battery is removed and is replaced by a 3-volt battery?

What happens when you connect the car positive and negative battery terminals together Will this reset car computers?
If you connect the terminals together with them unhooked from the battery and the engine off, yes that is also called a capacitive discharge.If you connect the terminals together with them unhooked from the battery and the engine off, yes that is also called a capacitive discharge.
When an auto mechanic drops a wrench across the two terminals of a car battery what happens?
A dead short occurs which can result in the battery exploding A completion in the external circuit of the battery
What happens if you charge a 12 volt battery backwards?
You cannot charge it connected backwards. You will destroy the battery.
What happens when a battery is connected wrong on a 1997 mercury villager?
you can blow fuses or the battery Possible computer damage.
1988 firebird gta 5.7L will not crank battery and starter is good?
take the battery terminals off and clean them and the battery posts real good with a wire brush and reinstall and see what happens.
